IMPROVEMENT IN LININGS FOR PUMP-CYLINDERS.

Specification forming part of Lettdrs Patent No. 145,895, dated December 23, 1873; application filed December 3, 1873.

To all whom t 'may concern:

Be itA known that I, WILLIAM S. OWEN, of Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Lift-Pumps, of which the following is a specification:

My invention relates to lift-pumps in which the plunger-valve works Within a metallic lining for maintaining a tight joint. Various lining devices have been contrived and secured in the pump-stock in diiierent ways for this purpose.

My improvement consists in providing the lower end of a cylindrical metallic lining with a separate cast-iron section, having its upper end recessed for iittin g into the lining, and at its lower end a rim which fits against the end of the pump-stock when inserted therein, the said section having a bore of less diameter than the pump-lining, and serving to form a seat at its inner end for the xed valve,

and a socket at its lower end for the pump,

pipe, thus utilizing` the separate iron section to support the lining in position, hold the Xed valve, and form a connection for the pump-pipe with the stock, and making a very cheap and durable device for the purposel In the accompanying drawings, Figure l represents a vertical section of a pump embracing my invention; Fig. 2, an elevation of the lining and its valve-section, and Fig 3 a modification of the same.

The lining A is a cylinder of thin metal, inserted into the pump-stock B, and within which the plunger-valve O works, and` is therebyprevented from getting loose by. wear.

This lining is fitted upon an iron section, D,

which has a recessed shoulder, a, for th at pur` pose, a-nd a lower flange or bead, b, which, when the section D is driven into the pump, fit-s against and is secured to the lower end of the stock. This plug D has a small bore, E, into which the pump-pipe F fits; and the Xed valve G is seated and secured upon the upper end of the section, and by this inea-ns is fitted in place with the pump-lining, being secured `to the end of the section before the latter is tted into the stock. The valve-section and lining are driven into the stock together, as

`like a telescope section, and secured to the pump-stock, must hold the lining in place. It may be used to rclit old pumps.

I claim- The pump-lining A having a separate section, D, for the fixed valve Gr and pump-pipe F, constructed and arranged for use as de scribed.
